Improvement in floor-gauge



y diluted mes JOEL FALES, OF CAMBRIDGE, MASSACHUSETTS.

Letters .Patent No. 94,814, dated September 14, 1869.

The Schedule refered to in these Letters Patent and making part of the same;

To all whom itmay concern v Be it known that I, JOEL FALES, of Cambridge,

county of Middlesex, and State of Massachusetts, have by which door-boards may be measured for cutting to the exact dimensions and angles required, without the slow process of measuring by rule and shaping by square; and my invention has been suggested to me by the inconveniences experienced in laying ioors and the time lost in measuring.

The nature of my invention consists in an adj ust'- able rod or rods, with movable try-gauges at each end, which readily adapt themselves to the angle of the door, while the length ofthe board is taken a once.

A and A are rods of suitable size and length.

B B' are lslides or shoulders, into which the rods' run, these rods being held in the slides by set-screws a a..

B B are additional slides or supports, used when more than one rod is employed. rlhese slides B B serv'e to'steady the gauge and preserve its straight-V ness.

c c are movable try-gauges, hung upon the pin d, att', and are held in any desired relation to the rods, by moving in a tight joint or by a set-scre\v.

The gauge may be adjusted to any length, by run ning the rods in the pieces B B', as desired. A sin-` gle rod is sufficient in ordinary rooms, but two or more rods may be employed, as shown, when greater length or stability of gauge is required.

f -Tlxe operation or .use of my gauge is asf'ollows:

Lay the gauge upon the floor, where a board is vto be put down, pushing th'e try-gauges c c flush up to the Walls at each side, and set the screws a c. This secures the exact length of board required, while the pieces c c determine at once the angle of the ends of the boards. All that is necessary then is to lay the gauge upon the board to be cut,and mark accordingly, thus obtaining quickly the precise dimensions desired.

A great amount of time is saved by this simple invention. j

When laying boards where one. or both sides of' the room are curved in either direction, I attach the trygauge shown in fig. 3, in place of gauge c. Thi-s tnygauge, for curved places, is constructed of pieces ee and m m, attached and turning on pins h 7L.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A oorgauge, composed of pieces d al, having shoulders or clasps B B, rod A, and try-gauges c c, or substitute shown in iig. 3, and set-screws a a, all constructed, arranged, and operating substantially as described and set forth.

2.I The combination of rods A A', pieces d d, having shoulders or-clasps B, supports B B', set-screws a a, and try-gauges e e, or substitute shown in iig. 3, the whole making a door-gauge, constructed, arranged, and operating substantially as shown and described, as and for the purposes set forth.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

Vitnesses: JOEL FALES.
